Ammonia storage issues in winter!
Thread Content
We have a process that requires ammonia. In winter, the ammonia storage tank is outdoors without insulation. In winter, temperatures here can reach below minus 35 degrees. What is the minimum concentration of ammonia that should be guaranteed? This post was last edited by snowdfr on 2009-3-4 13:06 ]
The concentration should be above 25%
It should be higher than 20%. There is a freezing point chart of ammonia concentration below. http://bbs.hcbbs.com/viewthread.php?tid=75722&highlight=%C7%EB%CE%CA%B0%B1%CB%AE%B5%C4%C4%FD%B9%CC%B5%E3%A3%A8%B1%F9%B5%E3%A3%A9%A3%BF
